Source Of Error
The source of error in this experiment occurs:
1. After you put the water into the graduated cylinder and then measure it and then pour the water out to test the next water sample, there is still water in the graduated cylinder and can be measured as more than it really is.
2. When going to the estuary and taking the water from it, some of the dirt could get in and mix with the salt and make it more dense.
3. From what I have tested some of the samples have no density.
Something that I might have done more is to find out more about the water samples.
Also I think that I would have done both of my tests with an electronic scale.
